Sometimes over time the sound quality on your telephone diminishes. It might be fuzzier than before, quieter, or non-existent. And the problem may not be that the person on the other end is talking any differently! It could be an electronic problem in your phone. Here are some simple ways you can improve the sound on your telephone.

How to improve the quality of sound that you’re sending to the other person
· Take apart the mouthpiece on your phone by unscrewing the cover. Lift the transmitter out of the phone (it generally just pops right out). Get a foam swab and dip it in denatured alcohol. Clean the dirt off the transmitting unit with the swab. Be sure to clean all parts of the transmitting unit: both plastic and metal. Get underneath every crack and crevice. The spots underneath the transmitter are often the most sensitive. Be sure to clean them carefully and thoroughly.
· Clean the metal parts of your phone. On the part of your phone that’s still attached to your phone in the transmitter cavity is likely gobs of dirt and grime. Clean the metal thoroughly and carefully with the swab with denatured alcohol. It’s amazing the difference clean contacts can have on a transmitting unit.

How to improve the quality of sound you’re receiving from the other person
· Take apart the earpiece on your phone by unscrewing the cover. Lift the microphone out of the phone (it will still be attached to the handheld receiver by a couple wires). Get a foam swab and dip it in denatured alcohol. Loosen all the screws a bit just enough to clean the leads thoroughly. If there’s any corrosion on the screws and leads, you may want to sand that off to provide for a clean, crisp sound.
· Reconnect each wire carefully and in its proper position. Screw them on tightly. Reassemble the handset.

This should offer you a much improved sound. If it doesn’t and you’re upset about the sound quality, you should have your phone professionally serviced.
